• EFFECT OF VISCOUS DISSIPATION ON MHD FLOW AND HEAT TRANSFER OFA DUSTY FLUID OVER AN UNSTEADY STRETCHING SHEET

Abstract

This paper is focused on the study of hydromagnetic boundary layer flow and heat transfer of a viscous, incompressible, dusty fluid over a stretching sheet with the effect of viscous dissipation. The equations of motion and heat transfer are reduced to system of coupled non-linear ordinary differential equations using similarity transformations. These non-linear differential equations are solved numerically by using RKF-45 method. The two different cases of heating process are studied, namely, (i) a sheet with variable wall temperature (VWT case) and (ii) a sheet with variable heat flux (VHF case). The effects of the various parameters entering into the problem on the velocity fields and temperature distributions are discussed both in graphical and tabular form. Comparisons of numerical results were made with previously published results.
